The Concise Valve Handbook, Volume I - Michael A. Crabtree - Bog - Momentum Press - Plusbog.dk

The Concise Valve Handbook, Volume I - Michael A. Crabtree - Bog - Momentum Press - Plusbog.dk

This two-volume book comprises a comprehensive up-to-date body of knowledge that provides a total in-depth insight into valve and actuator technology – looking not just at control valves, but a whole host of other types including: check valves, shut-off valves, solenoid valves, and pressure relief valves. Research studies within the process industry routinely indicate that the fluid control valve is responsible for 60 to 70% of poor-functioning control systems. Furthermore, valves in general are consistently wrongly selected, regularly misapplied, and often incorrectly installed. A methodology is presented to ensure the optimum selection of size, choice of body and trim materials, components, and ancillaries. Whilst studying the correct procedures for sizing, readers will also learn the correct procedures for calculating the spring 'wind-up' or 'bench set'. Maintenance issues also include: testing for deadband/hysteresis, stick-slip and non-linearity; on-line diagnostics; and signature analysis. Written in a detailed but understandable language, the two volumes are presented in a form suitable for both the beginner, with no prior knowledge of the subject, and the more advanced specialist.

Mechanical Blood Trauma in Circulatory-Assist Devices - Peter D. Wearden - Bog - Momentum Press - Plusbog.dk

Mechanical Blood Trauma in Circulatory-Assist Devices - Peter D. Wearden - Bog - Momentum Press - Plusbog.dk

Mechanical cardiovascular assist devices must be properly designed to avoid damage to the blood they contact. The factors that affect the hemocompatibility of a cardiovascular assist device include three major non-physiological components the material, fluid flow paths, and flow related stresses, - as well as the device interaction with the native vasculature. Furthermore, the interaction of the device with the blood is not static. Foreign surfaces activate blood components including platelets, leukocytes and the coagulation cascade. Thrombus formation on the surface of the device can alter the fluid dynamics in a manner that causes erythrocyte damage ranging from significant hemolysis to sub-lethal trauma that can take many days to weeks to develop into a significant clinical problem. This sub-lethal blood trauma is not easily detectable without special equipment, which is typically unavailable in routine clinical practice. Surveillance for blood damage is often sub-optimal in the clinical setting, but once clinically relevant hemolysis occurs, crucial decisions - device removal, replacement, or additional medical therapies including surgery or plasmapheresis - that take into account the risk/benefit of intervention must be quickly evaluated. The various preclinical designs and testing, surgical considerations, available surveillance techniques, and clinical consequences will be discussed using recent and historical case reports to highlight key points.

Catching the Process Fieldbus - James Powell - Bog - Momentum Press - Plusbog.dk

Catching the Process Fieldbus - James Powell - Bog - Momentum Press - Plusbog.dk

A field bus is a two-way link between a programmable controller or operations monitor and an industrial device like a sensor, an electric motor, or a switch. It is a critical part of any automated industrial process - whether for factory automation (discrete processes like an assembly line) or process automation (continuous flow of materials being mixed, treated, or processed). PROFIBUS is a widely established program that allows for communication among and between controllers, fieldbuses, and actuator devices. This very concise introduction for industrial engineers, controls engineers, and manufacturing technicians covers the basics of field bus architecture and communication and the fundamentals of the PROFIBUS language protocol.

Endoscopic Diagnostics in Biomedicine - N. Sujatha - Bog - Momentum Press - Plusbog.dk

Endoscopic Diagnostics in Biomedicine - N. Sujatha - Bog - Momentum Press - Plusbog.dk

Concise, yet comprehensive, coverage of various endoscopic forms as provided in this book will help the reader generate new knowledge in this field. Endoscopy has been in practice for many years in diagnostic medicine. From a simple image collection device, the endoscope has grown into an instrument that incorporates multiple imaging modalities to extract structural and functional information from different parts of the human body. Multimodality endoscopes are discussed in detail in this book, along with their clinical applications. The book is intended for graduate-level students as a quick reference to understand the evolving trends in endoscopic design research. The challenges that remain unaddressed could potentially be explored by biomedical researchers to advance this technology to realize the concept of optical biopsy during routine endoscopic examinations. The book portrays the endoscope as a purely optical instrument, and hence hybrid modes of endoscopic imaging are not covered.

BACnet; The Global Standard for Building Automation and Control Networks - H. Michael Newman - Bog - Momentum Press - Plusbog.dk

BACnet; The Global Standard for Building Automation and Control Networks - H. Michael Newman - Bog - Momentum Press - Plusbog.dk

BACnet is a set of data communication protocols, developed jointly by ASHRAE, ANSI and ISO, for how the automatic control systems in a building--from heating, to ventilation to lighting to fire control and alarm systems - can communicate with one another and, in turn, offer a centralized way for controlling all systems in a building. The author of this book H. Michael Newman presided as the chairman of the first effort to create this standard, and has been involved with updates and improvements ever since. The BACnet protocols are made use of in central control systems manufactured by companies like Honeywell, Siemens, and Johnson Controls, among many others. BACnet is widely used throughout the world today for commercial and institutional buildings with complex mechanical and electrical systems. Contractors, architects, building systems engineers, and facilities managers must all be cognizant of it and its applications. This book will offer those readers the ''inside wisdom'' from the person who actually helped to create this standard specification...making it easier to understand the intent and use of each of the data sharing protocols, the controller requirements, and the opportunities for inter-operability between different proprietary controllers and systems. Readers will appreciate: - The review of history of BACnet and its essential features, including the ''object model,'' data links, network layers, and BACnet systems - Coverage such services as alarm and event services, file access services, and remote device management services - Insight into future directions for BACnet, including wireless networking and network security
